Respuesta :

Answer:

-6.86 %

Explanation:

The percent of chance can be calculated as:

[tex]\frac{_{}\text{ final - initial}}{\text{ initial}}\times100[/tex]

So, replacing the final value by 52.5 years and the initial value by 56.1 years, we get:

[tex]\frac{52.5-56.1}{52.5}\times100=-6.86\text{ \%}[/tex]

Therefore, the percent change of life expectancy was -6.86 %. Where the negative sign means that there was a decrease in the average life expectancy.
